73 May the all-merciful Redeemer, who shortly before His death prayed to the Father that all who were to believe in Him might be one, just as He and the Father are one, (79) deign to hear this most ardent prayer of Ours and of the whole Church as quickly as possible, so that we may all celebrate the Eucharistic Mystery with one voice and one faith, and through sharing in the Body of Christ become one body, (80) joined together by the same bonds that Christ wanted it to have.
